The other contestants to enter the house last night were: former 'Holby City' actor Jeremy Edwards, better known for having been Rachel Stevens' boyfriend; sacked Radio One DJ Lisa l'Anson; model Caprice; Kenzie, a 19-year-old member of Blazin' Squad; and 80s actress and former Mrs Sylvester Stallone, Brigitte Nielsen.
Presenter Davina McCall also revealed that the housemates will be staying in the house for 18 days as opposed to 14, as previously released by the show's producers. The first two series of 'Celebrity Big Brother' only lasted for seven days.
The extended show will give Channel 4 the chance to earn considerable ad revenue from the ratings winner.
Bookmakers have already put their money on "mad for it" Bez winning the show with odds of 2-1. Ladbrokes spokesman Warren Lush said: "He has a cult follwing that could bring him victory."
Edwards, who also starred in Channel 4's Chester-based soap 'Hollyoaks', is second favourite at 4-1, while 'Female Eunuch' author Greer is a rank outsider at 16-1.
Nielsen, 41, has already caused a stir in the house by vowing to go topless.
"I'll be known as the one with the boobies, because I like wandering around with no top on," she said.
The other celebrities have already taken offence with the towering Danish actress.
"She's terrifying and I'm petrified and I don't care who knows it," Edwards said, while l'Anson added: "She's a mad big bird."
Elsewhere, McCririck, a self-confessed "boob fan", is unlikely to get on with Greer after admitting his idea of hell would be sharing a house with "a flat-chested, bossy woman -- someone like Germaine Greer."
The show will air weeknightly from 9pm with the Dermot O'Leary-fronted 'Celebrity Big Brother's Little Brother' at 11pm.
